Description
Technical Field
The invention belongs to the technical field of agricultural production, and particularly relates to a preparation method of a chelating sugar alcohol calcium ketone compound liquid.
Background
Calcium is an essential medium element for crop growth and plays an immeasurable role in plant growth. Calcium is a main component of plant cell walls and intercellular layers, and makes organs and individuals of plants have certain mechanical strength. In addition, calcium is a component and activator of some enzymes in plants, and has some influence on the metabolism of nitrogen and carbohydrates. Meanwhile, the calcium has the functions of eliminating some organic acids in the plant body, reducing the toxicity of the organic acids to the plant body and facilitating the absorption of potassium ions by the plant.
When the plant is in a calcium deficiency state, the growth of the root system is inhibited, the front end of the root is brown, the branches and leaves grow and are soft in texture, and the plant dies in a severe state (only the white root can absorb nutrition from the outside). The plant has short internodes, is short and small, is premature, is easy to fall down, is not fruitful or has less fruit bearing, and the fruit tree generally shows the phenomenon of fruit cracking. The grain crops have thin and small leaves and poor cold resistance and drought resistance; the rod is thin and easy to fall down, the ears are small and unsaturated, the yield is low and the quality is poor. The leaves are small, dark green and dull, the young leaves deform and curl, the leaf tips are bent, and the leaf edges become yellow and even scorched and necrotic when the leaves are serious.
In order to prevent crops from being lack of calcium, calcium nitrate, calcium chloride, calcium ammonium nitrate, chelated calcium and the like are commonly used for calcium supplement in agriculture.
However, when the inventor of the present application realizes the technical solution in the embodiment of the present application, it is found that the above-mentioned technology has at least the following technical problems:
since these calcium compounds are not easily absorbed and conducted in plants, the absorption and conduction of compounds such as calcium nitrate, calcium chloride, and calcium ammonium nitrate to crops are greatly affected, and calcium compounds in the form of chelated calcium partially solve this problem, but they are still not in a more desirable state.
In view of the above situation, how to find a product with higher crop absorption rate and further improve the calcium absorption rate of plants becomes an urgent task for those skilled in the art to solve.
Disclosure of Invention
In order to overcome the defect that calcium compounds are not easy to absorb and conduct in plants in the prior art, so that the absorption rate of crops to calcium is low, the embodiment of the application provides a preparation method of a chelated sugar alcohol calcium ketone compound liquid, and an applicant discovers through a large amount of research that a flavonoid substance is a trace substance which is formed in the evolution of plants and exists in the plants, plays an important role in regulating the growth of the crops in the crops and has a good carrying effect on the absorption of the calcium of the crops, so that the applicant determines the compatibility of wild pueraria flavonidus and the chelated sugar alcohol calcium through more than three years of research and development and hundreds of times of screening, develops a novel chelated sugar alcohol calcium ketone compound liquid compounded by the chelated sugar alcohol calcium and the vegetal flavone, improves the absorption utilization rate of the calcium, and further improves the yield, the chromaticity, the sugar content and the hardness of the crops better, has better social benefit.
The technical scheme adopted by the embodiment of the application for solving the technical problem is as follows:
a preparation method of a chelating sugar alcohol calcium ketone complex liquid comprises the following steps:
(1) adding calcium nitrate into water to be fully dissolved, adding sorbitol into the reaction system at the temperature, keeping the temperature until full reaction is finished, and cooling to room temperature to prepare chelated sugar alcohol calcium;
(2) cleaning wild radix Puerariae, slicing, placing into an extraction tank, adding extractive solution into the extraction tank, extracting, heating under reflux, extracting for three times, mixing the extractive solutions, and concentrating by distillation to obtain concentrated solution of total flavone of wild radix Puerariae;
(3) mixing the chelating sugar alcohol calcium and the wild pueraria flavonid concentrated solution to prepare the chelating sugar alcohol calcium ketone compound solution.
The chelated sugar alcohol calcium is a typical fast-acting foliar fertilizer, which can act on acid soil more smoothly, and the calcium in the fertilizer can neutralize the acidity in the soil. The method is particularly convenient for regenerative fertilization of winter crops, post (qualitative) additional fertilization of grains, excessive consumption of alfalfa growth fertilization, sugar beet, feed beet, poppy, corn, green feed mixtures and effective additional fertilization for eliminating the deficiency of plant calcium nutrition.
The flavonoids (flavanones) are compounds which exist in the nature and have a 2-phenyl chromone (flavanone) structure, and belong to plant secondary metabolites. They have a keto carbonyl group in their molecule, the first oxygen atom is basic and can form salts with strong acids, and their hydroxy derivatives are often yellow, so they are also called flavonones or flavones. Flavonoids are usually combined with sugars in plants to form glycosides, and a small part exists in the form of free form (aglycones). Most plants contain flavonoid compounds, which play important roles in plant growth, development, flowering, fruiting, antibiosis, disease prevention and the like.
The flavonoid compounds have wide application, and can be used as flavoring agent and natural antioxidant in food industry. Can be used as feed additive and growth regulator in animal husbandry. In the pharmaceutical industry, the compound can be used as an antitumor agent, an antiviral agent, a functional medicine for treating cardiovascular and cerebrovascular diseases and the like.
The plant flavonoids found at present are of hundreds of species, and the flavonoids are distributed almost throughout various tissues and organs of plants, such as leaves, roots, xylem, bark, pollen, flowers, berries, seeds and the like. In the plant growth, flavonoids are a part of signal bonds between plants and micro-symbionts, and are used as inducing substances to regulate the synergistic action of auxin in plants, so that the photosynthetic efficiency and metabolism of the plants are improved. Researches show that flavonoids play an important role in stimulating and promoting the absorption and conduction of mineral nutrients in the growth process of crops. The invention utilizes the characteristic of flavonoid to promote the absorption and the conduction of the chelating sugar alcohol calcium, thereby achieving the purposes of improving the fruit quality and increasing the yield of crops.

The embodiment of the application has the advantages that:
because the technical means of compatibility of the wild pueraria flavonid and the chelated sugar alcohol calcium is adopted, the problem of the absorption and utilization rate of the calcium by crops is effectively solved, and the absorption rate of the plant calcium is improved by 12 percent compared with the absorption rate of the plant calcium by singly using a calcium compound (calcium nitrate) and by 8 percent compared with the absorption rate of the plant calcium by using the chelated sugar alcohol calcium. The product is proved by multiple uses that the absorption rate of the crops to calcium is improved on various crops, the diseases of the crops are greatly reduced and the yield is greatly improved by regulating the growth of the crops through flavonoids, the yield is increased by 4-6% on apples through field tests, and better social benefits are obtained.
